From article <850@tucos.UUCP:, by sutela@tucos.UUCP (Kari Sutela):
: Well, I know this has been discussed quite recently, but at the time I wasn't
: paying too much attention. However, for some reason I ended up buying a 30 meg
: Supra HD for my A500 [well, other manufacturers' HD:s for the A500 just aren't
: available in Finland].
: 
: I want to know if anyone has succeeded in Mounting (and Formatting) this drive
: with non-Supra software (this possibility is mentioned in some readme-file, but
: no required technical information is given, though). I have tried a couple of
: times but have been unsuccessful so far.

	You should be able to just create a MountList entry for each of your
partitions, then use the AmigaDOS Mount command to mount each partition. The
A500 and A1000 versions of the Supra interface do this quite nicely. You'll
also end up saving about 10-15K per partition. Use a MountList entry similar
to the example on the 1.3 Workbench, but change the device drive name to
either harddisk.device or scsidisk.device, depending on which drive you have.

: BTW, SupraFormat shows that my drives are formatted with an interleave of 3.
: I think (based on Supra's ads) that one can use 0 interleaving with the 30-meg
: Supra drives/conrollers. Am I right? Can I damage things if I use too small
: interleaving? I doubt that I can cause any physical harm, BUT will it cause
: unreliability and/or soft errors?

	You can use a smaller interleave easily enough, just do a low-level
format with a smaller interleave, the only result you'll see is slower read
and write speeds. The interleave of 3 seems to be best for most drives with
the 500/1000 controllers, an interleave of 1 is best for the 2000s DMA card.

: Thanks in advance,
